Millimeter of Water Column (mmWC) to Millimeter of Mercury (mmHg) Pressure Unit Conversion Calculator

This calculator allows you to easily convert pressure values from Millimeter of Water Column (mmWC) to Millimeter of Mercury (mmHg), commonly used in meteorology, medical equipment, and low-pressure scientific applications.

The Millimeter of Water Column (mmWC) is a unit of pressure that represents the force exerted by a 1-millimeter column of water at 4°C. It is typically used for measuring low-pressure differences in systems such as HVAC, water distribution, and other low-pressure industrial applications.

The Millimeter of Mercury (mmHg) is a unit of pressure based on the pressure exerted by a 1-millimeter column of mercury at 0°C under standard gravity. It is frequently used in barometry, medical fields (e.g., blood pressure measurement), and vacuum systems.

Suppose you have a pressure of 500 mmWC.
To convert it to mmHg:

500×0.0735559=36.77795 mmHg

So, 500 mmWC is equal to 36.78 mmHg.

Millimeter of Water Column (mmWC)Millimeter of Mercury (mmHg)
1 mmWC0.07356 mmHg
10 mmWC0.73556 mmHg
100 mmWC7.35559 mmHg
500 mmWC36.78 mmHg
1000 mmWC73.56 mmHg
  • Medical Applications: Convert pressure values for medical devices like blood pressure monitors, where mmHg is a standard unit.
  • Meteorology: Useful for converting pressure readings in weather data between water and mercury columns.
  • Industrial Calibration: Applicable for converting low-pressure values in laboratory equipment and process control instruments.

This mmWC to mmHg conversion calculator is an essential tool for professionals working in scientific, medical, and industrial applications where precise pressure conversions are required.
